- 3 Claims.

This invention relates to a package for manually dispensing powder, suchas a garden insecticide.

It has heretofore been proposed to provide bellows containers fordispensing powder. However, most of these containers have been expensiveto manufacture and have had the disadvantage of not discharging thepowder uniformly and evenly. They have discharged an excessive amount ofpowder when new, and much powder has been wasted. I have devised animproved bellows container, which is inexpensive to manufacture andwhich discharges an even spray of powder on each compression of thebellows.

The container or package which I have devised consists of a paperenvelope including bellows folds connected between front and back panelsalong either side -of the envelope. Perforated cardboards are placedagainst the inside faces of the front and back panels of the envelope.The container tapers from an expanded end to a narrow end where a notchis cut to permit discharge of the powder. At the narrow end of thecontainer, the cardboards are arranged so that they prevent powder frompassing directly to the notch between their ends. The powder is thuscompelled to pass through the perforations in the cardboards and thencebetween the cardboards and the envelope in order to reach the notch.Each time the expanded end of the package is compressed a uniform sprayof powder is discharged from the notch. Y

Other objects, features, and advantages of the present invention willbecome apparent or will be pointed out in connection with the followingdetailed description of an illustrative package in accordance with theinvention, reference being made to the accompanying drawings wherein:

Fig. 12 is a view similar to Fig. 11, but with the closure in its nalposition as in Fig. 8, and with the notch cut in the package;

Fig. 13 shows a modified form of'cardboard construction; and

Fig. 14 is a side elevation of the cardboard of Fig. 13 folded and readyfor insertion in the envelope.

In Fig. 1 there is shown an envelope blank I5 which may be made out ofany suitable heavy paper. The paper is preferably water repellent. Theblank I5 is creased along the horizontal and vertical dot and dash linesand along the diagonal dot and dash lines, so that it can be readilyfolded to form the envelope. Dotted lines I6 are printed on the blank toshow where the notch is to be cut. 'I'he blank includes a centralportion I1 which forms the front panel of the envelope, portions 20 and2| which form the bellows, and portions I8 which together form the rearpanel of the envelope. The portions above the line e-f, including a apI9, are folded toform a closure at the small end of the package. Theportions below the line g-h form the other end of the package.

In making the package, the blank is first formed into a tube by bendingit around a suitable mandrel so that the edges of the panels I8 and I9abut or lie close together. A strip of paper 22, the same length as theblank I5, is pasted to the inside of the panels-I8. This strip 22, asbest shown in Fig. 9, or erlaps the panels I8 sufficiently to form atight closure. The panels 20 and 2I are then folded inwardly between thefront and rear panels I1 and I 8 with the fold between panels 20 and 2|lying at a-b-c-d as shown in Fig. 10. A gusset is formed by the twotriangular portions between the points b and c. It will be understoodthat instead of using a separate strip of paper 22, one of the panels I8may be made wider than the other so as to form a lap joint.

The cardboard used in the package are shown in Figs. 2 and 3 at 23 and24 respectively. Each of these cardboards is just a trifle smaller thanpanel Il and has a number of perforations or pin holes 26 formed in it.Cardboard 23 has a notch 25 cut in one end to coincide withfthe dottedlines I6. If desired the notch 25 may be made larger than the area I6.Cardboard 24 is creased along the line 21 and is slit as shown at 28 toform a flap 29 and hinged portions $0. Each of the portions 30 isapproximately the same width as the distance between the inner cornersof the bellows folds at the small end of the package. It will beunderstood that although cardboard has been mentioned as the material ofwhich the members 23 and 24 are made, other stiff material may be used.The number and size of the pin holes may be varied, and, if desired,such pin holes may be omitted from one of the cardboards.

After the envelope has been formed into tubular shape, the cardboardsare inserted in the envelope as shown in Fig. 5, the flap 29 being bentdown. The portions of the blank between the lines g--h and i-y' are thenpressed upwardly to form the end portions 36 and 31 of the package.' Theportions of the blank below the line i-y' are then doubled over andstapled as shown at 38 in Figs.' 6 and 11. The portions 36 and 31 arethen pressed inwardly to form a V as shown in Fig. 8. In this way, thetwo triangular portions of the gusset which lie between b and c in Fig,are doubled against each other.

In order to complete the package it is only necessary to ll it withpowder, fold the ap I9 and the portions of the envelope above the linee-f as shown in Fig, 8, and staple the doubled over portions of thepackage at opposite corners, so that the staples 39 pass through thehinged portions 30. The powder is thus sealed within the package.

. In order to discharge the powder from the package it is only necessaryto cut the notch in the envelope as shown in Fig. 12 and then grip thewide end of the package between the thumb and the ngers. Each time thatthe bellows are compressed powder is ejected through the perforations 26in the cardboards and thence between the cardboards and the front andrear panels of the envelope to the notch where the powder is dischargedfrom the package. By constructing the ap 29 as previously described thepowder is prevented from passing directly to the notch between the endsof the cardboards. The ap 29 also helps to expand the bellows. Byconstructing the envelope and cardboards as previously described, thefront and rear panels of the envelope bulge outwardly as shown in Fig. 8so as to leave room for the powder to reach the discharge notch.Inasmuch as the rear panel of the envelope is of double thickness, andtherefore stiffer than the front panel, it is preferable to insert thecardboard, including the flap 29, adjacent the rear panel. When thebellows are compressed, the front panel bulges up to the notch, whilethe rear panel bulges 'sumciently to permit powder to pass between itand the end 40 of the cardboard where ap 29 is hinged. It will be seenthat in the construction described, only the cardboard 24 is hinged tothe portions 3U. If desired, cardboard 23 may be made theA same as 24,and the flaps 29 on both members may be folded in to give additionalspring action.

In Figs. 13 and 14 there is shown a modied form of the cardboards 23 and24 in which both of them are scored on the dot and dash lines 21, and inwhich the two cardboards are made from a single sheet of material,including like portions 43 which are scored along the lines 44 and 45and which are cut away as indicated at 46. Fig. 14 shows the manner inwhich these cardboards are folded for insertion in the envelope.

My package thus comprises an inner container and an outer envelope, thepowder being retained in the inner container andbeing discharged uponthe compression of the bellows throughvperforations in the innercontainer and thence between the inner container and the outer envelopeto the discharge notch. y

The terms and expressions which have been employed are used as terms ofdescription and not of limitation, and there is no intention, in the useof such terms and expressions, of excluding any equivalents of thefeatures shown and described, or portions thereof, but it is recognizedthat various modications are possible within the scope of the inventionclaimed.

What I claim is:

l. A package of the character described comprising a tapering envelopehaving front and rear panels connected at either side by bellows folds,a pair of perforated cardboards lying within the envelope and adjacentthe front and rear panels. a discharge opening in the narrow end of theenvelope, means to prevent powder from passing directly to the dischargeopening between the ends of the cardboards, and means to close the endsof the envelope.

2. A package as claimed in claim 1, wherein the cardboards are just atrle smaller than the front and rear panels of the envelope, and

wherein the means to prevent powder from passing directly to thedischarge opening comprises a flap on one of said cardboards bent overagainst the other cardboard at the small end of the envelope.

3. A package as claimed in claim 1, wherein said cardboards are joinedby hinged sections.
